Subsurface Utility Engineering (SUE)

Subsurface Utility Engineering (SUE) is an engineering process that combines civil engineering, geophysics, survey and computer-aided design and drafting (CADD)/geographical information systems (GIS). Information on the location and condition of subsurface utilities is collated and assessed to reduce the occurrence of interference and conflict with valuable infrastructure.

Project and utility owners, designers, engineers and contractors can significantly benefit from adopting a SUE process during the life cycle of a project to avoid:
